小学英语时态语法总结之 – 一般现在时(Present

小学语法关于时态的部分大致可以总结为4个基本时态，一般现在时，一般过去时，一般将来时，以及一般进行时。今天我们要着重来总结归纳一下关于一般现在时的语法重点

一般现在时的定义(Basic concept)
英语中的一般现在时多用来表示生活中通常、经常发生的事情，具有习惯性、规律性的行为或者状态。其他也有用作客观存在的真理或者自然的一种规律。

基本结构 （structure）
表示主语状态时

主语 + be动词 (am, is, are)

当主语不是第三人称单数，谓语为实义动词（表示有实际意义的动词 ）时，

主语+动词原形

否定:主语+don't+动词原形

当主语是第三人称单数时

主语+动词原形（词尾要加s或es）
